POST-HOLE AUGER.

SPECIFICATION forming part of Letters Patent No. 233,931, dated November2, 1880.

Application filed To all whom it may concern:

Be it known that I, MEAD MILAM HUBBY, of Maysfield, in the county ofMilam and State of Texas, have invented a new and useful Improvement inPost-Hole Angers, of which the following is a specification.

Figure 1 is a side view of my improved posthole auger, partly in sectionto show the construction. Fig. 2 is a side view of the lower part of thesame turned one-quarter around.

The object'of this invention is to furnish an improved post-hole augerwhich shall be so constructed that it will bore post-holes easily andqnicklyin any kind of gravelly, clayey, or sandy soil, and which shallbe simple in construction, inexpensivein manufacture, and convenient inuse.

The invention consists in the diamond-shaped cutters having theirprojecting lower halves twisted, their points bent inward slightly, andtheir forward edges beveled, as hereinafter fully described.

Similar letters of reference indicate correspondin g parts.

Arepresents an iron tube twelve inches (more or less) in length andeight inches (more or less, according to the desired size of thepost-hole) in diameter. To the opposite sides of the upper part of thetubeAare securely riveted the lower ends of two bars, B, the upper endsof which are curved inward and upward and are riveted or bolted to thelower end of a bar, 0.

February .10, 1880.

The upper end of the bar 0 has an eye formed in it to receive a woodenhandle.

D are the cutters, which are made diamondshaped, and their upper halvesare securely riveted to the opposite sides of the lower part of the tubeA. The lower parts of the cutters D are twisted, and their points areslightly bent inward to give them a proper shape to work their way intothe soil. The forward edges of the lower halves of the cuttersD arebeveled to an edge to cause them to pass through the ground easily.

With this construction the auger will work its Way easily and rapidlyinto any kind of soil, will bring the soil with it when raised out ofthe ground, and may be easily emptied without its being necessary toinvert it for that purpose.

I am aware that it is not new to twist the part of bits below theholder, bend the same inwardly, and join their points into onescrewpoint but What I claim is 55 The cutters D, having about one-halftheir length twisted and projected beyond the tubeholder, the pointsbeing bent slightly inward and the forward edges beveled, as shown anddescribed.
